Abstract
Abstract5,5′‐Azo‐bis‐(5‐cyanocaproyl)‐benzoyl diperoxide was synthesized starting from 5,5′‐azo‐bis‐(5‐cyanohexanoic) acid, obtained in its turn from 5‐keto‐hexanoic acid, hydrazine sulphate and sodium cyanide.5,5′‐Azo‐bis‐(5‐cyanohexanoic) acid was then converted into acid chloride and condensed with perbenzoic acid. The structures of intermediates and of the product were elucidated by means of elemental analysis and IR and NMR spectral measurements.In order to settle the bifunctional character of the synthesized initiator the thermolysis rate constants for azo and peroxy groups, energies of activation and half‐life times were settled. By comparing the kinetic data with those obtained in 4,4′‐azo‐bis‐(4‐cyanovaleryl)‐benzoyl diperoxide thermolysis the decomposition rate was found to increase and the bifunctional character to enhance with increasing length of the radical connecting the azo and peroxy groups.
